creating a strikethrough text?

Question

Can I create a strikethrough text in Android, I mean adding a special value in the TextView tag that can make this possible?

Answer 1

If you are using Kotlin:

your_text_view.apply {
    paintFlags = paintFlags or Paint.STRIKE_THRU_TEXT_FLAG
    text = "Striked thru text"
}

Answer 2

In your observable view model

fun getStrikeContent(): String {
    return "Hello"
}


 companion object {
    @BindingAdapter("strike")
    @JvmStatic
    fun loadOldPrice(view: TextView, value: String) {
        view.text = value
        view.paintFlags = STRIKE_THRU_TEXT_FLAG
    }
}

then in your xml

     <TextView
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         app:strike="@{itemViewModel.strikeContent}" />

Answer 3

In Kotlin you can create extension property:

inline var TextView.strike: Boolean
    set(visible) {
        paintFlags = if (visible) paintFlags or Paint.STRIKE_THRU_TEXT_FLAG
        else paintFlags and Paint.STRIKE_THRU_TEXT_FLAG.inv()
    }
    get() = paintFlags and Paint.STRIKE_THRU_TEXT_FLAG == Paint.STRIKE_THRU_TEXT_FLAG

And use:

textView.strike = true

Answer 4

It is really easy if you are using strings:

<string name="line"> Not crossed <strike> crossed </strike> </string>

And then just:

<TextView 
        ...
         android:text="@string/line"
 />

Answer 5

Just use this and you are done . For Activity :

TextView t= (TextView).findViewById(R.id.thousand));
t.setPaintFlags(t.getPaintFlags() | Paint.STRIKE_THRU_TEXT_FLAG);

For Xml :

<RelativeLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content">

            <TextView
                android:id="@+id/text_view_original_cash_amount"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:padding="5dp"
                android:textColor="@android:color/darker_gray"
                android:text="Rs. 1,999"/>

            <View
                android:layout_width="wrap_content"
                android:layout_height="1dp"
                android:background="@android:color/darker_gray"
                android:layout_centerVertical="true"
                android:layout_alignStart="@id/text_view_original_cash_amount"
                android:layout_alignEnd="@id/text_view_original_cash_amount"
                android:layout_alignLeft="@id/text_view_original_cash_amount"
                android:layout_alignRight="@id/text_view_original_cash_amount" /> 
</RelativeLayout>
